The zoom mode is a state of the Image Editor in that invoked actions are performed in a normal 1X pel size image but are displayed to an operator in an enlarged, fat pel, zoom equivalent. When the ZOOM function is invoked a displayed zoom window is automatically centered upon a present position of a cursor as is also a selectively displayable viewport, the viewport showing the relative position of the cursor within the 1X image.

Why it's free to use
- Filed March 22, 1990 and granted March 5, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
